Replace the ad-hoc appearance panel with a uniform table (sync icon | name |
value): dropdowns instead of button groups, every colour with a reset to a
canonical default, a per-row sync toggle, and a global "sync all" master
switch.
- new settings-sync.js: canonical default colours, declarative table
definition, browser-local value copy, effective-value resolution
- calendar.js: generalised sync engine (pull applies only synced keys from the
server, save pushes only synced keys + the flag map), unified the two save
buttons into one, dropped the dead text/line-contrast code, moved default
duration into the appearance table, effective UI language on load
- account settings (private visibility, group calendar, hide profile) stay in a
dedicated profile block, not the sync table
- app.css: settings table / sync toggle / sync icon styles
- i18n: sync-all / sync-this / share-icon strings; sw cache bump
